Now why would the police go to all that trouble and expense to lure miscreants to
friend them on Facebook when they can access (for free) the FBI facial recognition database full of driver's license and other photo ID pix and then search that database for criminal records?
Hmm, maybe that's why I never met many of those cops at Mensa meetings.

And, just how is the typical person going to build their own Facebook based facial recognition database or flag those people already on Facebook who happen to be criminals? Or is that a new Facebook service?
Due to my spinal cord injury (in layman's terms my headbone is no longer connected to my neckbone), I rarely leave my residence and have no need of a smartphone or security cameras so I cannot provide step-by-step instructions. Those who do can set things up to get a text message alert when the doorbell rings and then they connect to their security cameras and use their low-tech eyeballs to see who's at the door. And, if their teenage daughter lets a stranger in, they can ground her, cancel her allowance or, horror of horrors, confiscate her smartphone until she learns her lesson. Or, perhaps, just call 911 and report a prowler.
Anyway, my motto is "facepalm, frequently - faceplant, rarely - Facebook, NEVER!"
